Is fire always a relief case

[DLLV]

In case of an totally filled MEA extraction tower it will take a while to heat up the inventory until vaporization starts. This can take minutes or even hours using for energy balance the API formular. If the fire will extinguished before what happens within this time. For some companies this is a way to avoid this case and a flare system.
Is there any experience available?

Thanks for your interest

Another case for relief, in MEA towers, can be blocked discharge, and the PSV discharges to drum and flare.

The transient heatup time is not a factor in deciding whether to protect a vessel against fire overpressure.
If a pool fire is credible, then pressure protection is required.
